a modified formofthe air conchanism with parts shown in sec- In thedrawing, reference character l() represents the bore of a well in whicha portion of the pumping apparatus is placed, this portion consisting ofcylinders 11A and '12 mounted in superposed fashion butseparate fromeach other. The cylinders are provided with integral partitions 13 and14 respectively dividing the cylinders into two parts,

the larger of which forms Vthe inlet sideand the smaller partition 13 incylinder llextends the. full length and completely separates the inletfrom the outlet side. In the lower cylinder 12, the partition 14 extendsdownwardly. but

the discharge side thereof. The

does not reach the bottom thereby allowing liquid to flo w from one sideto the other. The' cylinders are provided`with narrow4 inlet openings 15 and 16 respectively extending almost the entire length of thecylinders, each provided with inwardly extending valve seats on wh ichrest flaps 17 and 18 these being ing fluid to the cylinders from acontrol mechhinged at 19'and 20 and operating within the cylinders. Thelength of the cylinders may vary and in order to insure quick fillingany number of additional inlet valves may be used, h5 A pipe 21 connectsthe discharge pipes of the two cylinders and is provided Vwith a one-waylvalve 22 which permits' liquid to pass from the dischargeside-ofcylinder 12 s p to the discharge side of cylinder 11 and out- 60ward to a common discharge pipe23to any desired p-oint, this pipe 23being connected to thevupper end V of the discharge side of cylinder1 1. 4

A pipe 24 is connected tothe bottom of cylinderll and is'joined to pipe21 at a point 25 intermediate the valve 22 and the lower end of thedischarge side ofcylinder 11 and is provided withya one-way valve 26,similar y tovalve 22, permitting liquid to pass fromthe 70 cylinder lltopipe 21, hence outward through the common discharge 23. Pipes 27 and 28connected to the upper. ends of the cylinders 11 and-12respectively andconvey the operatanism as will now be described.

h The control mechanism consists of a valve structure 29,. The upperportion 30 is provided with anoutwardly extending flange 31 on its loweredge and an arm 32,. The lower portion 33 is cup-like inl .structure andhas a iiange'34, corresponding to iange 31, on its upper e-dge by whichthe parts 30 and 33 are secured together by any suitable means. Thecenter portion 35.01 the valve is nested in the lower portion 33 andprovided with packing rings 36 to form a tight but rotatable connectionwithrespect to the upper andlower portions.A The center portion isprovided i with inlet passage ways 37'and 38 each dia- 90 metricallyopposite exhaust ports 39:and'40A respectively. The inlet passagesextend through this portion and in line with the cor-y` respondingpassages in the upper and lower 9,. portions' depending on the positionof the center portion). The exhaust ports extend partially into thecenter portion and are turned at right angles to the outside edge.Corresponding ports 41 and 42 are'bored in the lower section to conformwith the exhaust ports 40 and 39 respectively.

A lever 43, extending through a slot 43 in the lower portion 33 isconnected to the center portion and is operated by a rod having aslotted bar 44 on one end and connected at the other end to a piston 45operable in a cylinder 46. The piston 45 is operated by means ofcompressed air from the pipes 27 and 28 and conveyed to each side of thepiston by pipes 46 and 47. The needle valves 48 and 49 control the flowof the air to the cylinder 46.

A pin 50 secured to thelever 43 extends into y the slot in the bar 44serving as a connection between the rotating portion 35 and the piston45. A pin 51 of greater length than Ypin 50 is'xed to the lever 43 andspaced from the slotted'bar 44 at a distance to move without engagingthe bar. A similar pin .52 is secured to the arm 32 and a spring 53 isconnected between the last named pins serving to snap the mechanism backand forth as the spring moves in and'out of parallel alignment with thelever 43.

The lower portion ofthe valve structure is connected to pipes 27 and 28and the upper portion'to p'i es 54 and 55 which merge into a single suppy pipe 56 connected to av tank 57 of compressed gas or air and suppliedby the pipe 58 from a compressor not shown.

Inthe modified form Fig. 5 a valve operating on the same principle asthat just 'described is 'shown but of slightly dil'erent structure. Thevalve consists of a sliding central portion 59 provided lwith passages60 and 61 and exhaust'ports 62 and 63. a The upper section 64 p and thelower section "65 are secured together by an'ysuita'ble means. A bar 66is secured or 'madeintegral with the sliding section 59 and is providedwith a pin 67 at its free end. The slotted end 68 of the piston rod 70engagesthe pin 67, .said slotted end68 being actuated by a piston 71v onthe piston rod 7 01 operating in cylinder 72. The piston is operable bycompressed air4 or gas from lines 73 and 74 connected to line 75 and 76respectively which carry air to the main cylinders in the well from thecontrol valve. Pipes 77 and 78 supply the main valve with compressed airfrom a suitable supply.

A curved bracket 79 is mounted on the upper section 64 of the vvalve andis provided with a link 80 pivoted to its free end Aa't'81.v

The link 8O is provided with a: slot 82 which engages -a ypin 83 on thebar 66. The free end of the link 80 is connected to a point 84 of thebracket 79 by a spring 85 in a manner to move with the bar 66 t'o theright or left as the case may be and cause afsnapmovement ofthe bar 66as the .spring 85 moves in Vand out'of parallel alignment with respectto the link 80.

The operation of the above described apparatus is as follows Compressedair or gas flows from the supply tank or any suitable source through themain pipe line 56 and hence to the valve which is in the position asindicated by Fig. 2. The passage way 38 is in line with the pipes 53 and27 permitting the operating fluid to flow into the pipe 27 forcing thevalve 17 shut and the liquid which is in the cylinder 11 through thepipe 24, pipe 21 and then outward through the pipe 23. Valve 22 prevents'the liquid from entering the cylinder l2.

VAt the same time part of the compressed air enters the Ipip-e 46V andthe piston 45 is gradually moved to the right forcing the slotted bar 44carrying the lever 43, and rotating the section 35 slowly in acounter-clockwise direction until the spring has'passedfa line parallelwith the lever and then it will snap to its extreme position due to thevaction of the spring. As the compressed air enters the cylinder l1 thevalve 18 lin the cylinder 12 opens, the incoming water forcing thetrapped air upward through the pipe 28 which is in line with the exhaustport 40. As soon as the piston 45 has reached the position opposite tothat shown in Figure 2 the passageway 37 Vis then in line with the pipes28 and Y55, the exhaust port y39 lines up with the pipe 27. Air isforced through the pipe 28 to the cylinder 12 forcing the valve 18 shutand the uliquid outwardly through the discharge side into the pipe 21and thence to the discharge pipe 23. vThe valve 26 prevents theliquidfrom entering the cylinder 11. Meanwhile the incoming water against thevalve 17 in the cylinder 11 forces the air out of this cylinder throughthe ,pipe 27 to the exhaust port 39, thus completing one pumpingstrokeof the pumping apparatus and which always insures constant flow of waterfrom lthe cylinders. The rapidity of operating is controlled by theneedle valves 48 and 49 to the valve operating piston. The form shown inFigure 5 operates substantially the same in principle excepting foralsliding horizontal rather than rotatable control valve.
